McDonald's has launched a bizarre new food item on its menu in China - a sandwich complete with SPAM and crushed Oreo pieces. The launch of the new burger has sparked debate over the unusual combination.

A UK resident who had visited China shared McDonald's promotional pictures on Twitter. The post immediately went viral, with people on the internet criticizing McDonald's for creating such an abomination.

"McDonald's China is introducing a new Oreo x SPAM burger on December 21. There will be 400,000 produced and sold," the tweet said.

The original owner of the post followed up with another tweet, saying that even people in China "hate" the burger. He also pointed out that McDonald's is an American chain and the Chinese weren't to blame.

"Doesn't sound even remotely tasty. If they said just SPAM, ok... odd but ok. But Oreos on a burger of any type is disgusting," a user on social media said.

While some people online were disgusted by the unusual combinations, others expressed their interest in trying out the unique burger. One user said that someone from McDonald's must have proposed the idea and the burger had to taste good if it was allowed to be added to the menu.

Some users had questioned whether or not it was really crushed Oreos that was placed in the burger. In McDonald's promotional material, SPAM was indicated as a registered trademark in the fine print - Oreo was not. One user said that McDonald's could be using a similar product from another brand.  

Over the past decades, fast food restaurants have been attempting to create dishes that combine sweet and savory flavors. Last year, Domino's launched a "bubble tea" flavored pizza in Taiwan topped with black sugar pearls, cheese, and honey.

Domino's gamble had paid off as some customers expressed their fondness of the pizza's unique flavor combination.

"Omg it's incredible. They nailed it. Not joking, everyone here needs to try this. The pizza is savory, but it's sweetened with honey on top, the boba aren't mushy," one customer wrote on social media.
